MORRIS VUERIEL, OF ST. LOUIS, MISSOURI.

BALANCED VALVE.

SPECIFICATION forming part of Letters Patent No. 397,825, dated February 12, 1889.

Application led April 30, 1888.

To all whom t may concern:

Be it known that I, MORRIS WUERPEL, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Balanced Valves, of which the` is the cap litted to the other end of the body.

These parts are held together by bolts 4. They may be fitted together with groundjoints at 5 and 6, or the joints may be made tight with gaskets. The cap has a .fiat plate, 7, whose rim ts the end of the barrel, and a neck, S, into Which a pipe may be screwed. The plate? has a number of curved apertures or ports, 9, Within which is the bearing l0 for the head or upper annular face, 12,013 the valve proper, l1. 13 pressed against the face l0 by springs be This face has packing-ring neath it, so as to exclude the fluid passingy through the valve from the interior ll of the valve ll. Theinteriorcavity,14,0f the valve has no special purpose, except lightening the Weight of the valve. The lower part of the valve has a fiat disk, l5, with a ground-bearing on the seat 16 of the piece 2. This disk has a port or aperture, 17, Which, when the valve is in the position shown, is in line with the port or passage I8, extending through the piece 2. The disk l5 has upon it abevel cogl Serial No. 272,352. (No model.)

segment, 19, engaged by a bevel-wheel, 20, upon a shaft, 2l. The shaft 2l passes through a stuffing-box, 22, within which it has a collar, .3, preventing the ondwise movement ot the shaft.

At 24 is shown a hand-crank, by which the Shaft is turned.

It will be seen that by turning ihe valve one-half around the parts 17 and 1S are closed, as they only extend about one-third around the disk la and seat l5, and are then out of line with each other.

This form of valve is specially applicable where it is needed that the valve shall be easily adjusted as to the area of the passage, for, being balai'iced, it is easily turned, and the hand-shaft and cog-connection give ready meansA for turningl the valve a very little distance.

I claiml. The combinaiion of the valvelhhaving a disk, l5, working uponthe seat lo, and having a port, 17, adapted to be brought in line with the port I8 of the seat-piece, and having' a head, l2', with packing-ring bearing againstv the plate '7, which has apertures 9 outside the line of bearing, substantially as and For the purpose set forth.

2. The valve ll, having bearing upon iis seat 16, and an expanding head, l2, with ringpackiug against the plate, a cog-sector, 19, upon the valve, a cog-Wheel, 20, engaging the cog-sector, and a hand-shaft carrying the cogwheel and passing through a stuffingbox, 22,

as set forth.
